What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

The TSD Rally Clock allows you to synchronize to the Official Rally Time by making adjustments in increments of +/– 0.1seconds to account for total errors of as much as + or – 10 seconds. Touch the Lock icon to make clock adjustments. Adjust time ahead or behind as needed and, when finished, touch the Unlock icon to prevent unintended adjustments. Touch the double Arrows singly or continuously to make adjustments in +/– 0.1 second increments. When unlocked a chime will sound at 0 seconds and 30 seconds. This audible cue is helpful when synching with the Official Rally Clock. To clear the list of split times, touch the "Clear Log" button and answer the question "Yes." Start the rally by touching the clock face. Recording split times can be helpful for comparing your time at a checkpoint to the time recorded by the checkpoint staff. Or, the checkpoint staff could use this feature to record times as cars cross a checkpoint. Also, split times can be used to track time in what are called Regularity or Jogularity style rallies. The current split time and the cumulative time will be logged in a table and compare these times with those indicated on the route instructions to see how well you are maintaining the ideal pace. On the clockface displays, time can be measured in either seconds or decimal minutes. Additionally, there are two levels of time precision. One displays two digits for seconds or two digits for hundredths of a minute. For more precision, the other measures and displays seconds as two digits plus tenths of a second or three digits for thousandths of a minute. There are three watch face styles: black, yellow, and white.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
